Description

Technical Field

[0001] This invention relates to the field of BIM technology, and more specifically, to a method, device, and medium for generating BIM-based electromechanical pipeline clearance height information. Background Technology

[0002] BIM stands for Building Information Modeling or Building Information Management. BIM uses various relevant information and data of a building project as a foundation to build a three-dimensional building model and simulate the real information of the building through digital information. It has eight key characteristics: information completeness, information relevance, information consistency, visualization, coordination, simulation, optimization, and the ability to generate drawings. BIM is not simply the integration of digital information, but rather an application of digital information and a digital method for design, construction, and management. This method supports an integrated management environment for building projects, significantly improving efficiency and greatly reducing risks throughout the entire process.

[0003] In the existing technology, the layout of each pipe on the two-dimensional drawing can only be processed manually, and the net height of the area after the pipe layout is completed must be calculated manually. Especially in large-scale complex projects, the building area is particularly large and the electromechanical pipelines are numerous and complex, resulting in extremely high time costs for manual calculation.

[0048] This invention provides a method for generating BIM-based MEP (Mechanical, Electrical, Piping) integrated overhead height information. Please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic flowchart of a first embodiment of a BIM-based method for generating MEP (Mechanical, Electrical, and Piping) overhead height information, provided by an embodiment of the present invention. The method includes:

[0049] S11 generates three-dimensional electromechanical and piping drawings based on the pre-set two-dimensional CAD drawings of the building. The basic two-dimensional CAD drawings include architectural drawings, structural drawings, water supply and drainage drawings, HVAC drawings, and electrical drawings.

[0050] Optionally, three-dimensional electromechanical and piping system drawings can be generated based on the pre-set two-dimensional CAD drawings of the building.

[0051] In the optional scenarios, the preset building can be a residence, a commercial complex, a hospital, a school, a cultural center, etc., without limitation. During the design process, it is necessary to draw basic 2D CAD drawings for the preset building, covering architectural, structural, plumbing, HVAC, and electrical disciplines. These basic 2D CAD drawings include architectural drawings, structural drawings, plumbing drawings, HVAC drawings, and electrical drawings.

[0052] After obtaining the basic two-dimensional CAD drawings for each specialty, the basic two-dimensional CAD drawings can be processed to generate three-dimensional electromechanical and pipeline drawings.

[0053] Optionally, Revit software, Chenxi BIM intelligent model conversion software, or other BIM software for automatic model conversion can be used to process and generate 3D MEP (Mechanical, Electrical, and Piping) drawings. No specific limitations are made here.

[0054] S12, based on the three-dimensional electromechanical pipeline drawings and the two-dimensional CAD drawings, obtain the floor height information and beam height information of each floor in the preset building, as well as the area information of different areas of each floor.

[0055] Subsequently, based on the basic two-dimensional CAD drawings, the floor height and beam height information of each floor in the preset building, as well as the regional information of different areas of each floor, can be obtained.

[0056] Optionally, information on the floor height and beam height of each level, as well as regional information for different areas, can be obtained from architectural and structural drawings.

[0057] In optional scenarios, the floors may include basement floors, standard residential floors, and standard office floors. Taking a basement floor as an example, its different areas include driveway areas, parking space areas, ramp areas, etc. The floor height and beam height information will differ for different floors or different areas of the same floor. Similarly, the overall floor height and beam height information may also differ for different floors; for example, the floor height and beam height information of basement floors, commercial floors, and residential floors are all different.

[0058] S13, Based on the pipes in the three-dimensional electromechanical pipework drawings and the preset electromechanical pipework layout rules, determine the electromechanical pipework layout scheme for each area in different areas of each floor.

[0059] Subsequently, based on the pipes in the 3D electromechanical pipeline drawings and the preset pipeline layout rules, the electromechanical pipeline layout scheme for each area in different regions of each floor was determined.

[0060] In an optional embodiment, by obtaining the electromechanical pipeline layout scheme for each area, the control height of the electromechanical pipelines in the corresponding area can be determined.

[0061] Optionally, the piping in its 3D electromechanical piping drawings will specifically include the electromechanical piping from various basic 2D CAD drawings, such as water pipes in water supply and drainage drawings, air ducts in HVAC drawings, and cable trays in electrical drawings. Water pipes are categorized in various ways, such as pressure pipes, gravity pipes, hot water pipes, etc., without specific limitations here. Similarly, HVAC ducts include smoke exhaust ducts, fire-fighting air supply ducts, and fresh air ducts. Likewise, its cable trays include general-purpose high-voltage cable trays, high-voltage fire-fighting cable trays, low-voltage cable trays, and fire-fighting electrical cable trays, without specific limitations here.

[0062] In basic 2D CAD drawings, the pipes of each discipline are independent and their layout is completed. However, after generating 3D MEP (Mechanical, Electrical, and Piping) integrated drawings, since the pipes of each discipline are mapped onto the 3D MEP integrated drawings, collisions between the pipes of each discipline will occur on the 3D MEP integrated drawings. Therefore, it is necessary to rearrange the pipes of different disciplines and obtain the MEP integrated layout plan for each area (underground garage parking spaces, underground garage driveways, residential standard floors, office standard floors, pipe shaft entrances and exits, refuge floors, etc.).

[0063] Please see Figure 3 Optionally, based on the pipes in the 3D MEP (Mechanical, Electrical, and Piping) drawings and the preset MEP layout rules, the MEP layout scheme for each area in different zones of each floor is determined. Further steps are as follows:

[0064] S131: Obtain the electromechanical clearance height control requirements for each area in different regions of each floor of the building.

[0065] In an optional embodiment, the electromechanical clearance height control requirements for each area in different zones on each floor of the building can be obtained.

[0066] Optionally, the mechanical and electrical clearance height control requirements can be manually input or customized to take into account different building developers. For example, if the preset building belongs to Vanke or Jinmao, the corresponding mechanical and electrical clearance height control requirements will also be different.

[0067] Optionally, in one embodiment, the electromechanical control requirements are specifically as follows: b) The clearance height of ordinary lanes is generally controlled at 2.4m or above; c) The clearance height of garbage lanes is generally controlled at 3.0m or above; d) The clearance height of truck lanes is generally controlled at 2.8m or above. The clearance height of ordinary parking spaces is generally controlled at 2.2m or above, and the clearance height of mechanical parking spaces is generally controlled at 3.1m or above. The clearance height of equipment walkways is generally controlled at 2.45m or above. The requirements for underground parking spaces, underground parking lanes, underground parking spaces, residential standard floors, office standard floors, pipe shaft access locations, refuge floors, etc., vary for each area on each floor, and are not specifically limited here.

[0068] S132: Obtain the installation control height of electromechanical pipelines based on the floor height information and beam height information corresponding to each area, as well as the electromechanical clearance height control requirements.

[0069] Subsequently, the installation control height of electromechanical pipelines can be obtained based on the floor height and beam height information corresponding to each area, as well as the electromechanical clearance height control requirements. In an optional embodiment, for a basement parking space, the building floor height is 4000mm, the beam height is 700mm, and the electromechanical clearance height requirement for the underground parking space is 2600mm. The calculated installation height of the electromechanical pipelines is: 4000mm - 700mm - 2600mm = 700mm.

[0070] S133: Based on the control height of electromechanical pipelines and the preset pipeline layout rules, the electromechanical pipelines of each area are arranged so that each area meets the electromechanical clearance control requirements.

[0071] In an optional embodiment, once the control height of the electromechanical pipelines in a certain area is determined, the layout and optimization of the electromechanical pipelines in the area can be continuously carried out to ensure that the area meets the electromechanical clearance control requirements.

[0072] The following is one embodiment:

[0073] S1331: Based on the preset electromechanical pipeline layout rules, if the electromechanical clearance height control of different areas on each floor cannot meet the requirements, then return to step S13.

[0074] S1332: Optimize the layout rules of electromechanical pipelines, optimize the layout of electromechanical pipelines, or reduce the control requirements for electromechanical clearance height, thereby obtaining a higher control height for the installation of electromechanical pipelines.

[0075] In an optional embodiment, when each area of ​​different zones on each floor is a beam-slab structure area, the duct layout is optimized, with the ducts installed directly against the bottom of the beam (typically, the top of the duct is 50mm away from the bottom of the beam), thereby optimizing the space by 50mm.

[0076] In an optional embodiment, the mechanical and electrical clearance height control requirement is reduced, thereby obtaining a higher control height for mechanical and electrical pipelines. Specifically, taking a basement parking space as an example, with a building floor height of 4000mm and a beam height of 700mm, the initial requirement for the mechanical and electrical clearance height of the underground parking space is 2600mm, which is then reduced to 2500mm. The calculated control height for mechanical and electrical pipelines is: 4000mm - 700mm - 2500mm = 800mm. Thus, the control height for mechanical and electrical pipelines increases by 100mm.

[0077] The pre-set electromechanical pipeline layout rules are as follows:

[0078] In an optional embodiment, the electromechanical pipeline layout scheme for each area is not only related to the pipeline's own parameters, but also to its routing method and the parameters of each area itself. Therefore, the pipelines in each area need to be laid out according to preset pipeline layout rules.

[0079] In an optional embodiment, if the area information indicates that the area is a flat slab area, then the cable rack is located below the air duct and above the water pipe. That is, in a flat slab area, whether the cable rack, air duct, and water pipe are parallel or intersecting, the air duct should be placed at the top, the water pipe at the bottom, and the cable rack in the middle.

[0080] In another alternative embodiment, if the area information indicates that the area is a beam-slab structure area, then the water pipe is located below the cable rack and above the air duct. That is, in a flat slab area, whether the cable rack, air duct, and water pipe are parallel or intersecting, the cable rack should be placed at the top, the air duct at the bottom, and the water pipe in the middle.

[0081] In an optional embodiment, the water pipe also includes a pressure pipe and a gravity pipe, namely a pressure pipe that enables flow through pressure and a gravity pipe that enables flow through gravity. When the pressure pipe and the gravity pipe intersect, the pressure pipe avoids the gravity pipe by bending, thereby reducing the amount of bending in the gravity pipe and preventing fluid accumulation.

[0082] In an optional embodiment, different pipes have different diameters. That is, when two pipes intersect, one has a larger diameter than the other and is referred to as the larger diameter pipe, while the other is referred to as the smaller diameter pipe. Therefore, the smaller diameter pipe needs to be maneuvered to avoid the larger diameter pipe, thereby reducing pipe maneuvering costs.

[0083] In an optional embodiment, the pipeline also includes metal pipelines and non-metal pipelines, specifically metal pipelines with a metal outer shell and non-metal pipelines with a plastic or similar outer shell. If the pipeline indicates an intersection between a metal pipeline and a non-metal pipeline, the metal pipeline will avoid the non-metal pipeline. Optionally, because metal pipelines have better extensibility and flexibility, the avoidance range can be effectively increased, reducing processing costs.

[0084] In an optional embodiment, there are also spacing requirements between the pipes, which must be met whether they are two parallel pipes or two perpendicular pipes.

[0085] Optionally, two parallel pipes need to meet a first spacing requirement, and two perpendicular pipes need to meet a second spacing requirement.

[0086] In optional scenarios, water pipes include water supply pipes, air ducts include ventilation ducts, and cable trays include high-voltage cable trays, low-voltage cable trays, and high-voltage cable trays. When two water supply pipes run parallel, their spacing must be 100mm; when two water supply pipes are perpendicular, their spacing must be 50mm. Whether water supply pipes and ventilation ducts are perpendicular or parallel, their spacing must be 100mm. When water supply pipes run parallel to high-voltage cable trays, low-voltage cable trays, or high-voltage cable trays, their spacing must be 300mm; when perpendicular, their spacing must be 150mm. Further details are omitted here.

[0087] S14. Based on the floor height and beam height information of each floor, as well as the regional information of different areas of each floor and the electromechanical pipeline layout scheme, determine the net height information of each area.

[0088] Subsequently, based on the regional information of different areas of each floor, as well as the floor height information and the beam height information, the actual beam height information of the electromechanical pipelines in each area is determined.

[0089] In an optional embodiment, the actual height of the electromechanical pipelines under the beams in each area can first be determined based on the area information, floor height information, and beam height information of different regions on each floor. Some areas have beams, and some areas do not. For areas with beams, the actual height of the electromechanical pipelines is the difference between the floor height information and the beam height information. For example, if the floor height is 4000mm, the beam height is 800mm, and the slab thickness is 120mm, the beam height generally includes the slab thickness, so the actual height under the beams is 4000-800=3200mm. If there are no beams in an area, the actual height under the beams is the floor height information minus the slab thickness. For example, if the floor height is 4000mm, the beam height is 0mm, and the slab thickness is 120mm, the actual height under the beams is 4000-120=3880mm.

[0090] Optionally, the net height information for each area is determined based on the actual beam height information of the electromechanical pipelines and the electromechanical pipeline layout scheme. Optionally, the control height of the electromechanical pipelines in each area is determined through the electromechanical pipeline layout scheme, and then the difference between the actual beam height information of the electromechanical pipelines in the area and the control height of the electromechanical pipelines is obtained and used as the net height information of the electromechanical pipeline installation in that area. 。

[0091] Subsequently, based on the net height information of the electromechanical piping installation, a recommended ceiling height diagram is calculated. Specifically, the recommended ceiling height diagram is the difference between the net height information of the electromechanical piping installation and the height of the ceiling joists.

[0092] In the above embodiments, a three-dimensional MEP (Mechanical, Electrical, and Plumbing) integrated drawing is generated based on a pre-defined two-dimensional CAD drawing of the building. This pre-defined two-dimensional CAD drawing includes architectural drawings, structural drawings, water supply and drainage drawings, HVAC (Heating, Ventilation, and Air Conditioning) drawings, and electrical drawings. Based on the three-dimensional MEP integrated drawing, the floor height and beam height information of each floor, as well as the area information of different regions on each floor, are obtained. Based on the pipes in the three-dimensional MEP integrated drawing and the pre-defined pipe layout rules, the MEP integrated layout scheme for each region on each floor is determined. Based on the floor height and beam height information of each floor, the area information of different regions on each floor, and the MEP integrated layout scheme, the net height information of each region is determined. This allows for the automated acquisition of the pipe layout method for each region and the determination of the net height information for each region, effectively reducing labor costs and improving computational efficiency.

[0093] Please see Figure 2 , Figure 2 This is a schematic flowchart of a second embodiment of the BIM-based MEP (Mechanical, Electrical, Piping) integrated height information generation method provided by the present invention. The method includes:

[0094] S21, perform collision detection on the three-dimensional electromechanical pipeline drawings and obtain a collision detection report.

[0095] In an optional embodiment, a collision detection report can also be obtained by performing collision detection on the three-dimensional electromechanical manifold drawings.

[0096] Specifically, it can also be achieved using the collision detection module that comes with the BIM software, which will not be elaborated on here.

[0097] S22. Based on the floor height information, beam height information, and net height information of each area, determine the height map of each floor. The height map includes the floor height map, beam height map, mechanical and electrical pipeline installation control height, actual beam height information of mechanical and electrical pipeline (actual beam net height filling height map), mechanical and electrical pipeline installation net height information, and ceiling suggested height map.

[0098] Subsequently, the height map of each floor can be determined based on the floor height information, beam height information, and net height information of each area. The height map includes the floor height map, beam height map, mechanical and electrical pipeline installation control height, actual beam height information of mechanical and electrical pipeline (actual beam net height filling height map), mechanical and electrical pipeline installation net height information, and ceiling suggested height map.

[0099] S23, use the collision detection report and the height map of each layer to generate a report document.

[0100] Optionally, after obtaining the collision detection report and the height maps of each layer, a report document can be generated based on the collision detection report and the height maps of each layer. The report document can be a PPT document, which can be generated by inputting the collision detection report and the height maps of each layer into a standard PPT template.

[0101] In summary, this application provides a BIM-based method for generating MEP (Mechanical, Electrical, and Piping) system clearance information. It generates three-dimensional MEP system drawings based on basic two-dimensional CAD drawings of the building, including architectural, structural, plumbing, HVAC, and electrical drawings. Based on these three-dimensional MEP system drawings, it obtains floor height and beam height information for each floor of the pre-defined building, as well as area information for different zones on each floor. Based on the pipes in the three-dimensional MEP system drawings and pre-defined pipe layout rules, it determines the MEP system layout scheme for each zone on each floor. Based on the floor height and beam height information, area information for different zones on each floor, and the MEP system layout scheme, it determines the clearance information for each zone. This method automates the acquisition of pipe layout information for each zone and determines the clearance information for each zone, effectively reducing labor costs and improving computational efficiency.
